Official summary
Audi: avoiding damage to haldex clutch and final drive. The haldex clutch's oil filler plug and drain plug must not be confused with the final drive's oil filler plug and drain plug. The integrated housings of the haldex clutch and final drive, the drain plugs and the filler plugs of the two systems are often mixed up. This leads to avoidable maintenance mistakes, which can cause the malfunction of the haldex clutch or the final drive. *pe

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
